device 100 is usable with aconventional clothes line 300 having an elongated loop configuration having aproximal end 302 thereof located adjacently a firststationary support 304, and a distal end thereof engaged on a distalclothes line pulley 306 rotatably mounted to a secondstationary support 308 spaced apart from the firststationary support 304. Theclothes line 300 includes alower portion 310 to which clothes and other items can be hanged, and anupper portion 312 completing the loop formed by theclothes line 300. - The
device 100 includes anelongated guide 102. Theguide 102 is attached to the firststationary support 304 and extends typically substantially vertically, generally transversally relative to the elongated loop configuration of theclothes line 300. Furthermore, theelongated guide 102 defines a pair of laterallyopposed rails 105 extending longitudinally therealong and atoothed rack 104 provided between therails 105 and typically facing outwardly relative to the firststationary support 304. The firststationary support 304 may take the form of a vertical post, as illustrated inFIG. 1 , of a wall, or any other suitable stationary structure. - The
device 100 further comprises adrive unit 106. Thedrive unit 106 includes abody 108, which for example forms a housing receiving an actuating assembly including components used to handle theclothes line 300. Thebody 108 is mounted to theguide 102 and movable longitudinally therealong. For example, thebody 108 is movable along therails 105 and includes arail engaging portion 110 engaging therails 105 so that the only degree of freedom of thebody 108 relative to therail 105 is the translation motion along theguide 102. If needed, bearings, rollers or other structures are provided to facilitate translation of thebody 108 along theguide 102, but a simple sliding motion is also possible. - Referring now collectively to
FIGS. 2, 5 and 6 , thedrive unit 106 further includes apulley 124 mounted to thebody 108 for mounting theclothes line 300 thereto and anactuating assembly 107 operative for selectively moving thebody 108 along theguide 102 and for selectively rotating thepulley 124 to move theclothes line 300 when theclothes line 300 is also mounted to anotherpulley 306 and looped around the two 124 and 306 under tension.pulleys - The actuating assembly includes first and second worm drives 112 and 114 operative respectively for rotating the
pulley 124 and moving thebody 108 along theguide 102. Each one of the first and second worm drives 112 and 114 is located within thebody 108 and includes aworm screw 116 having an outer peripheral portion thereof in driving engagement with aworm gear 118 rotatably mounted within thebody 108. Thefirst worm drive 112 is configured so that rotating itsworm screw 116 results in rotation of thepulley 124, and thesecond worm drive 114 is configured so that rotating itsworm screw 116 results in movements of thebody 108 along theguide 102. - The worm screws 116 are located longitudinally spaced apart from each other coaxially in register relative to each other along a common axis and each define a
worm passageway 122 extending longitudinally axially therethrough The worm passageways 122 define each aninternal gear 120 at ends thereof that are facing each other. - In a typical arrangement, the
worm gear 118 of thesecond worm drive 114 forms a pinion that has a peripheral portion thereof in driving engagement with therack 104, forming a rack and pinion arrangement. Also, thepulley 124 is typically parallelly coupled on a same rotational axis of theworm gear 118 of thefirst worm drive 112 and engages theproximal end 302 of the elongated loop configuration of the clothes line 300 (as best illustrated inFIG. 2 ). Theclothes line 300 extends through thebody 108 through suitablysized apertures 126. If required, additional gears or gear boxes may be provided between the first and second worm drives 112 and 114 and respectively thepulley 124 and therack 104 to provide suitable movement speeds. - The
drive unit 106 further includes anelongated drive shaft 128 extending longitudinally slidably through each one of theworm passageways 122 coaxially in register with the common axis thereof. Thedrive shaft 128 is configured for being able to selectively alternatively engage the first and the second worm drives 112 and 114. To that effect, thedrive shaft 128 extends through theworm passageways 122 so that a main shaft portion thereof is freely rotatable relative thereto. Furthermore, thedrive shaft 128 is provided with first and second engagement gears 130 and 132 protruding radially from the main shaft portion at longitudinally spaced apart locations therealong and jointly rotatable therewith. - The
drive shaft 128 is movable between drive shaft first and second positions wherein thedrive shaft 128 respectively engages the worm screws 116 of the first and second worm drives 112 and 114 so as to be jointly axially rotatable therewith and is disengaged respectively from the second and first worm drives 114 and 112. More specifically, the first and second engagement gears 130 and 132 are configured and sized for engaging only one of theinternal gears 120 provided in the first and second worm drives 112 and 114 when thedrive shaft 128 is respectively in the drive shaft first and second positions so that thedrive shaft 128 and an engagedworm screw 116 from the first and second worm drives 112 and 114 engaged by one of the first and second engagement gears 130 and 132 are jointly rotatable. - The
drive unit 106 further includes a bidirectionalelectric motor unit 134 located within thebody 108 and having anoutput shaft 136 adapted to be in rotational driving engagement with thedrive shaft 128 when the latter is in the drive shaft first and second positions. - The
